TRACK-OILING DEVICE.

SPECIFICATION forming part of Letters Patent No. 756,617, dated April 5, 1904.

Application filed August 8,1903. Serial No. 168,815. (No model,)

To all whom it may concern:

Be it known that I, ARTHUR M. FRAzEE, a citizen of the United States, residing at Hebron, in the county of Licking and State of Ohio, have invented a certain new and useful Improvement in Track-Oiling Devices, of which the following is a specification.

This invention relates to means for applying oil to railway-tracks, and has for its object to provide an improved apparatus of this character which is arranged for actuation by the compressed air of the ordinary air-brake system, and while applicable to any type of railway is particularly designed for use in connection with interurban electric railways.

Another object of the invention is to arrange the apparatus for applying oil to the inner edge or side of the tread portion of the rails and to have'the discharge-nozzle normally in an elevated position and capable of being depressed under the action of the compressed air to bring the nozzle in position for properly directing the oil against the rail.

With these and other objects in View the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention. The single figure of the drawing illustrates a sectional view of the apparatus of the present invention in its general relation with re spect to one of the rails of a railway-track.

The present apparatus embodies a tank 1 for containing oil and is secured to the bottom frame of a railway-car in any suitable manner. Leading through the top of this tank is an air-pipe 2, which is in communication with the air-supply pipe of the ordinary air-brake system and includes a three-way valve 3, which is ordinarily located in the vestibule of the car or at least in position for convenient manipulation by the motor-man. If used in connection with a steam-railway,

the controlling-valve will of course be located in the cab of the locomotive.

Independent of the oil-tank 1 and secured to the bottom frame of the car is a verticallydisposed cylinder 4t,having a reduced top extension 5, which is divided internally by means of a vertical partition 6, terminating short of the top extension and dividing the latter into substantially parallel passages 7 and 8, both of which communicate at their lower ends with the interior of the cylinder proper. Communication is had between the cylinder and the oil-tank by means of a pipe 9, one end of which pierces the top of the tank and extends nearly to the bottom thereof, while its opposite end connects with a nipple 10 on the extension 5 and communicates with the lower portion of the passage 7.

' Working within the cylinder 4: is a piston 11, which is limited in its upward movement by the reduced extension 5 and has its downward movement limited by an internal shoulder 12 upon the cylinder. Centrally piercing the piston and carried thereby is a tubular pistonrod 13, the upper end of which works in the passage 8 of the extension 5 and its lower end pierces the bottom of the cylinder and is bent laterally to form an elbow 14:, atthe outer end of which is a horizontally-disposed spray-nozzle 15. A helical spring 16 embraces the piston-rod within the cylinder, with its lower end bearing against the bottom of the cylinder and its upper end bearing against the under side of the piston,-thcreby to yieldably hold the latter at its upper limit. The top of the piston-rod is closed, and suitable perforations or openings 17 are formed through the sides of the upper portion of the piston-rod to constitute ports therefor.

Under normal conditions or at least when not in use the hollow piston-rod is held at its upper limit by the spring 16, thereby elevattank 1, thereby applying pressure upon the surface of the oil and forcing the same up through the oil-pipe 9 into the passage 7 of the extension 5, through which it rises and presses against the closed top of the pistonrod and also against the piston 11, thereby forcing the latter and the piston-rod downwardly until the ports 17 pass downwardly through the lower open end of the passage 8 and thereby into communication with the oil within the cylinder, which enters the tubular piston-rod and escapes through the nozzle 15 against the adjacent side or edge of the tread portion of the rail 18. When the controllingvalve is closed, the pressure is relieved and the piston-rod and nozzle are returned to their normal positions under the influence of the spring 16, whereby the ports 17 are again closed and communication between the oiltank and cylinder is effectually cut ofii. When the pressure of air on the oil is relieved, the air is exhausted by turning the three-way valve.

Having thus described the invention, what is claimed, and desired to be secured by Letters Patent, is

1. In an apparatus of the character described, the combination of an oil-tank having means for connection with a source of fluid-pressure, a cylinder in communication with the oil-tank and having a piston for actuation by the oil entering the cylinder, and a discharge-nozzle connected with the piston to be raised an lowered thereby.

2. In an apparatus of the character described, the combination of a cylinder, a piston therein, a tubular piston-ro'd piercing the cylinder with its outer end provided with a discharge-nozzle, and an oil-tank in communication with the cylinder and having means for connection with a source of pressure to force the oil from the tank to the cylinder and into the tubular piston-rod.

3. In an apparatus of the character described,

the combination with an oil-tank, of a cylinder, a piston therein, a tubular piston-rod piercing the cylinder with its outer end provided with a discharge-nozzle, that portion of the pistonrod which is within the cylinder having inletports that are normally closed, said pistonrod being movable with the piston to uncover the ports thereof, and means to admit pres sure to the oil-tank to force oil into the cylindex and the piston-rod.

1 In an apparatus of the character described, the combination with an oil-tank having means for admitting pressure thereto, of a cylinder having achamber therein with an open end, a tubular piston-rod having one end piercing the cylinder and provided with a dischargenozzle, an intermediate portion of the rod having ports and fitting within the chamber of the cylinder with the walls of the chamber normally closing the ports, and a piston connected to the rod and movable therewith to clear the ports of the walls of the chamber and admit oil to the piston-rod.

5. In an apparatus of the character described, the combination of a cylinder having a contracted chamber in one end thereof which is open at its inner end, a tubular piston-rod having one closed end portion working in the chamber and provided with a port normally closed by the walls of the chamber and movable through the open end of the chamber to open the port, the opposite end of the rod being provided with a discharge nozzle and piercing the cylinder, a piston carried by the rod, a spring bearing against the piston to normally hold the rod within the chamber, and means for admitting oil under pressure into the cylinder and at the opposite side of i the piston.
